Application filed January 5, 1914. Serial No. 810,311.

To all Grimm itin/1y concern Be it known that we, Guonos A. SAUER, Jr., and lli'sssm. A. 'lla-wu. citizens of the United States, residing at Dayton, in the count)T of Montgomery and State oi Ohio, have invented certain new and useful lmprovonients in Cookers for Seeds and .the like, of which the followiluef is a specification. ri-iferenc'e being had therein to the accompanying drawing.

This invention relates to cookers for seeds and the like preparatory to extracting the oil therefrom. Cookers of this kind comprise a plu alit-y of receptacles arranged one above the other, each receptacle being adapted to discharge into the receptacle next below it. The material in each receptacle is agitated by means ot an arm or sweep which tends to spread the seeds or meal and inasmuch as this sweep is rotatively mounted at one end at the center of the receptacle its tendency is to move the seeds or meal toward the outer periphery of the receptacle. As a result it is customary tovarrange the discharge opening near the outer periphery of the receptacle. However, the seeds or meal will be more evenly distributed within the receptacle and therefore more evenly acted upon by the heat therein it they are deposited in the receptacle near the center thereof. this being duc again to the tendency of the sweeps to movc the meal toward the outer periphery ot the receptacle.

The object ot the present invention is to provide means whereby the meal discharged from an upper receptacle near the outer periphery thereof may be deposited in a lower receptacle near the center thereof; and Jfurther. to provide means for automatically controlling the discharge ot meal from sa id upper receptacle.

A. further object is to provide such a mechanism which will be simple in its construction and positive in its operation.

ln the accompanying drawings, Figure l is a side elevation, partly in section, of a cooker embodying the invention; Fig. 2 is a top, plan view ot' a portion ot such a cooker; and Fig. 3 is a detail view of the actuating gears for the cut-off.

i In these vdrawinltrs we Shave illustrated one embodiment of the invention and have showntthe same as applied to a cooker ot a well known type, in which the several recep tacles are superposer] one above the other in `Each receptacle, except the bottom one, is

provided with a discharge opening 6 arranged near the outer periphery thereof. The lower receptacle is also provided with a discharge opening' but as this has no part in the operation of the present mvention 1t is not here shown. The operation of the cooker is well known and it consists in depositing the seeds or meal into the upper receptacle and causing the same to be discharged at intervals through the discharge opening of this receptacle into the receptacle 2 and thence after an interval into the receptacle 3 where the cooking is completed and from which the completely cooked seeds are eventually discharged. The seeds or meal may be deposited in the upper receptacle at any convenient point but owing to the tendency of the arms or sweeps 5 to move the meal toward the outer walls of the cookers it is preferable thatI the discharge opening should be near such outer wall. For the reasons above riven it is also desirable that the meal shou d be deposited near the center of the lower cooker into which it is discharged. To accomplish this we have provided a suitable device by means ot which the meal may bc conveyed from the discharge opening of the upper receptacle to a point near the center of the lower rcceptacle. This device may be ot any suitable character but, in the torni here shown, ir comprises a trough 7 arranged beneath the discharge opening ot the upper receptacle 100 and adapted to receive the meal discharged through said opening. This trough extends inwardly to a point near the center of the lower receptacle and is provided with a discharge opening, in the present instance, the 105 trough being open-ended. A suitable actuating device is placed within the trough to move the meal along the same toward the discharge end thereof. ln-the present instance this actuating device is in the form of a screw 8 journaled at its opposite ends in suitable bearings carried by the trough and having its outer end projecting beyond the side of the cooker where it is connected with j'jsuitable driving devices, such as a sprocket chain 9 extending about sprocket wheels 10 and 11 carried by the shaft of the feed screw and by a drive shaft 12, which latter is provided with a suitable driving member, 'such as a belt pulley 13. It will be ap- Aparent, therefore, that as the meal is discharged into the trough it will be conveyed toward the center of the lower receptacle and discharged therein, and that in this manner the sweeps or arms will act onl the meal in such amanner as to provide a uniform distribution of the same within the receptacle. The meal is discharged from the receptacles only at intervals and in order that this discharge may be automatically controlled a gate 14 is provided to control each discharge opening 6. This gate is, in the present instance, a sliding gate and is connected at its outer end by means of a pin and slot connection with one end of a lever 15 pivotally supported between its ends upon a bracket 16, The opposite end of the lever 15 is bifurcated and the two portions thereof,- which are shown at 17 and 18, are in the` form of cams and are arranged in the path of a stud or projection 19 carried by an arm 20 secured to and rotating with a vertical shaft 21, which shaft is rotated in a manner hereinafter to be described. The arm 20 rotates in the direction of the arrow in Fig.

2 and it will be noted that the projection 1S) will first engage the arm 17, thus rocking the lever 15 in a direction to open the gate 14. When the gate has been opened the projection will pass the arm 17 and the gate will remain open during the intervals required for the projection to pass from the arm 17 to the arm 18 which, when engaged by the projection, will swing the lever 15 in a direc tion to close the gate, the gate then remaining closed during the interval required for the projection to pass from the arm 18 tof` thefarm 17. These movements may be timed in any sultable manner.

and the projection 1t), is rotated slowly through suitable gearing arranged near the :l bottom thereof. The conveyers and operating devices for the gates for the several dlsrangement, although not essential to the operation of the present invention.

The shaft 21 may be driven in any suitable manner,

a worm wheel 23 on a short vertical shaft In the present inf stance, the shaft 21, whlch carries the arm 2() In the present instance the power shaft 12 has a worm 22 meshing with 24 arrangedparallel with and alongside the lower portion of the shaft 21.. Mounted on the shaft 24 is a one-toothed piuion`25 arranged to mesh with a gear 20 on the shaft 2l tendin to rotate the same intermittent-ly. In order tat the gate may be quickly opened and closed means are provided for accelerating the movement of the shaft 21 at the proper times. Y The pinion has connected therewith and arranged above the same two extra teeth 27, in the form of a short segmental rack. The gear 26 is also provided at intervals about its periphery with superposed additional teeth, as shown at 28, in the form of short segmental racks. Consequently, when the extra, or accelerating teeth on the pinion engage the extra teeth or rack on the gear the movement of the gear and, consequently, the shaft to which it is secured, will be accelerated and carried for- Ward continuously a distance sufficient to Y complete the movement of the gate.

The operation of the device will be readily understood 'froml the foregoing description and it will be apparent that the meal will be deposited near the center of each receptacle and that the gates controlling the discharge of the meal will be automatically opened and closed at predetermined intervals, thereby enal'iling the cooking of the meal to be properly timed and causing the meal to be evenly distributed so thatv the cooking of the meal will be uniform.

While we have shown and described one embodiment of the invention it will be understood that this has been chosen for the purpose of illustration only and that we do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
